SAFETY INSTRUCTIONS:

CAUTION: To reduce the risk of electric shock, do not remove the top cover. No user-serviceable parts inside. Refer servicing to qualified service personnel only.
The lightning flash with the arrowhead symbol within the equilateral triangle is intended to alert the use or the presence of un-insulated “dangerous voltage” within the product’s enclosure that may be of sufficient magnitude to constitute a risk of electric shock.
The exclamation point within the equilateral triangle is intended to alert the user to the presence of important operation and maintenance (servicing) instructions in the literature accompanying this appliance.
This symbol means: indoor use only
This symbol means: Read instructions
This symbol means: that this amplifier is capable of producing very high sound pressure levels that may permanently damage your ears. Hearing experts strongly advise against permanent exposure to high sound levels!

To prevent fire or shock hazards, do not expose this appliance to rain or moisture.
To avoid condensation to be formed inside, allow the unit to adapt to the surrounding temperatures when bringing it into a warm room after transport. Condense sometimes prevents the unit from working at a full performance or may even cause damages.
This unit is for indoor use only.
Don’t place metal objects or spill liquid inside the unit. No objects filled with liquids, such as vases, shall be placed on this appliance. Electric shock or malfunction may result. If a foreign object enters the unit, immediately disconnect the main power.
No naked flame sources, such as lighted candles, should be placed on the appliance.
Don’t cover any ventilation openings as this may result in overheating.
Prevent use in dusty environments and clean the unit regularly.
Keep the unit away from children.
Inexperienced persons should not operate this device.
maximum safe ambient temperature is 40°C. Don’t use this unit at higher ambient temperatures.
The minimum distance around the apparatus for sufficient ventilation is 10cm.
Always unplug the unit when it is not used for a longer time or before you start servicing.
The electrical installation should be carried out by qualified personnel only, according to the regulations for electrical and mechanical safety in your country.
Please use the original packing when the device is to be transported.
Due to safety reasons, it is prohibited to make unauthorized modifications to the unit.

INSTALLATION GUIDELINES:

Install the unit in a well-ventilated location where it will not be exposed to high temperatures or humidity.
Placing and using the unit for long periods near heat-generating sources such as amplifiers, spotlights, etc. will affect its performance and may even damage the unit.
The unit can be mounted in 19-inch racks. Attach the unit using the 4 screw holes on the front panel. Be sure to use screws of the appropriate size. (screws not provided)
Take care to minimize shocks and vibrations during transport.
When installed in a booth or flight case, please make sure to have good ventilation to improve heat evacuation of the unit.
To avoid condensation to be formed inside, allow the unit to adapt to the surrounding temperatures when bringing it into a warm room after transport. Condense sometimes prevents the unit from working at full performance.

CLEANING THE APPLIANCE:
Clean by wiping with a polishing cloth slightly dipped with water. Avoid getting water inside the unit. Do not use volatile liquids such as benzene or thinner which will damage the unit. Clean the ventilation holes regularly with a vacuum cleaner. This increases the cooling capacity of the amplifier fans and helps prevent temperature overheating.
CONNECTIONS
Be sure to turn off the unit before you make changes to the wiring. For the signal inputs, we recommend using the XLR connections. Use good-quality signal cables to ensure excellent audio quality. For the speakers, you must use the Speakon ® compatible outputs. In the description of the unit, you will find more information on how to connect the amplifier.

FUNCTIONS (FRONT)

SYNQ SE 1800 Two Channel Digital Power Amplifier -
FUNCTIONS

VENTILLATION HOLES: during its operation, the amplifier produces heat that needs to be dissipated. The fans inside the amplifier must be able to evacuate the heat in the most effective way. Therefore, is it very important not to cover any of the ventilation openings as this may result in overheating? Clean the ventilation holes regularly with a vacuum cleaner. This increases the cooling capacity of the amplifier fans and helps prevent temperature overheating.
GAIN CONTROLS: These potentiometers are used to control the input sensitivity of the amplifier. Each channel has its own control. You can use these controls to set the maximum sound level of your setup:
• Turn both controls on the amplifier to the left
• Put on some music and make sure the VU meters on your mixer are at 0dB. (from time to time the red zone is lit)
• Set the Master output from your mixer to the maximum.
•Open the Gain controls from the amplifier until the maximum desired sound level is reached.
• Make sure nobody can reach the Gain controls of the amplifier. You have just set the maximum level the DJ is able to produce. Your neighbors will be glad… ☺ (in some cases the DJ is not )
Note: In Mono and Bridge mode, only the gain control of the left channel is used to adjust the input sensitivity.
LCD DISPLAY: shows all kinds of real-time information like audio input level, mains voltage, working temperature, and fan speed.
SIGNAL LEDS: these LEDs indicate that a music signal is present at the inputs.
CLIP LEDS: The LEDs will light up in the following situations:
• When the output signal has reached a high level which can result in distortion (clipping). Meanwhile, the current limiters come into action to reduce the dynamic range (current) of the output and bring the amplifier back to its safe working range. In this case, you are urged lower the input!
PROTECT LEDS: The protection LED is on in the following situations:
• During the first second after switching on the amplifier.
• When the temperature of the power stage becomes too high.
• In case of a technical defect: DC protection!
• While switching the amplifier off, the “protect led” turns on for a short time.
MAINS SWITCH: Used to turn the amplifier on and off. A few seconds after switching on the amplifier it is ready for operation.
FUNCTIONS (REAR)
MAINS INPUT with PowerCON ® compatible socket, connect the supplied mains cable here.
MAINS FUSE: protects the unit in case of electrical problems, always use the prescribed 30×6 mm ceramic fuse!
FAN & VENTILLATION HOLES: during its operation, the amplifier produces heat that must be dissipated.
The fans inside the amplifier must be able to evacuate the heat in the most effective way. Therefore, is it very important not to cover any of the ventilation openings as this may result in overheating?
L+R OUTPUTS: use the Speakon ® compatible connectors (preferred) or the red/black wire terminals to connect your speaker cabinets. Wiring is as follows:
• STEREO / MONO MODE:
• CH1:POS(+) = PIN1+ NEG(-) = PIN1- (left channel) POS(+) = PIN2+ NEG(-) = PIN2- (right channel)
• CH2: POS(+) = PIN1+ NEG(-) = PIN1- (right channel)
Remark: this means that CH1 could be used as output for both left and right channels…
• BRIDGE MODE:
• CH1: POS(+) = PIN1+ NEG(-) = PIN2+ (mono bridge, use left input)
• CH2: output not used
Remark: when the wire terminals are used in bridge mode, the speakers connected to the 2 RED colored terminals: POS(+) = RED terminaCH1 * NEG(-) = RED-terminal CH2
OPERATION MODE: to choose the most adapted operation mode for your application:
• STEREO MODE: This is the most common mode, both channels are working separately.
• MONO MODE: Basically, this is identical to stereo mode but the inputs of both channels are linked so the output will be mono. This means that you only need to use the CH1 input to drive both output channels.
• BRIDGE MODE: Both channels are linked in “bridge mode” to obtain a mono output with a much higher power.
INPUT SENSITIVITY SWITCH: you can choose 3 different input levels: 0,75V / 1V / 1,5V
LF ENHANCER: adds low-frequency compensation to enhance the low-frequency balance. The final result of this compensation varies according to the connected speaker cabinet type.
BALANCED XLR OUTPUTS: Can be used to send the signal to the next amplifier. Pin1: signal ground, Pin2: signal+, Pin3: signal –
BALANCED COMBO INPUTS: these connectors accept both JACK 6,3mm and XLR 3pin.
• XLR-connector: Pin1: signal ground Pin2: signal+ Pin3: signal –
• JACK-connector: SLEEVE: signal ground TIP: signal+ RING: signal –
FAN MODE SWITCH:
• Silent mode: minimum fan noise for use in the recording studio, theatre, …
• Power mode: maximum cooling for use in rough conditions like discotheques, and summer festivals, …
